Hmm, wasn't even aware about it
.
However, unchecked, config burned, nothing has changed.
I checked ini files before try, it download 4 new files but nothing has changed for me.
Also I tried to rollback to 1.38, still the same.
Any other idea what to check ?
I am considering if it takes maybe noise of the sparks or something, but it is not periodical, doing it even in idle and randomly ..
